Have a question about how the TVTropes wiki works? No one knows this community better than the people in it, so ask away! Ask the Tropers is the page you come to when you have a question burning in your brain and the support pages didn't help.
It's not for everything, though. For a list of all the resources for your questions, click here. You can also go to this Directory thread

Corsswicking is between work page and trope page, not work page and creator page. Creator pages really shouldn't have anything that can't go to their specific work pages, unless something doesn't have a page or is common among multiple works.

The Bury Your Art crosswick is on me, sorry; I saw trivia tropes wicked on creator pages in the past and assumed that was allowed. I'll go ahead and remove it from Creator.Gigi DG.
Be kind.
It's my understanding that trivia tropes are very much allowed on creator pages, unless the rule has changed lately.
I serve at the pleasure of President Pritchart.
If there are multiple works of the creator's that the trivia applies to, sure, list it on the creator article and individually on each work.
This might warrant a larger discussion, but Trivia tropes that are 'biographical' are IMO fine to add on both work and creator page even if it doesn't recur, like Romance on the Set and Died During Production.
If a trivia example is listed on the trivia page for a work, would it be redundant to also list it on the page for the work's creator, or is that just crosswicking?
This concerns an example of Bury Your Art (listed on both Gigi D.G. and Trivia.Hiimdaisy) and an example of Died During Production (listed on both Terry Pratchett and Trivia.Discworld)
I'm leaning toward "if it's already listed on the trivia page for a work, remove it from the creator page" but wanted to get some second opinions.
